⚡ Static Electricity
Discover the invisible forces of static electricity! Learn how rubbing objects together builds up electrical charges, how these charges attract or repel each other, and why some materials conduct electricity while others block it. Through safe, hands-on demonstrations, explore the science behind clinging balloons, sparking jumpers, and the way static electricity makes light objects dance. Perfect for Grade 3 learners exploring forces and the invisible world of electrical charges. **What you'll learn:** - How friction causes static electricity to build up on objects - Why charged objects attract or repel each other - The difference between conductors and insulators - Real-world examples of static electricity in action

- Question 1
When you rub a balloon on your hair, what causes the static electricity to build up?
- Question 2
Static electricity can only occur when two objects are wet.
- Question 3
Why does a charged balloon stick to a wall?
- Question 4
If you rub two balloons on your hair and then bring them close together, what happens?
- Question 5
Copper is a conductor, which means it allows electricity to flow through it easily.
- Question 6
Which material is an insulator?
- Question 7
When you take off a wool jumper in winter, you sometimes see sparks or feel a shock. What causes this?
- Question 8
Insulators prevent electricity from flowing through them, making them useful for safety.
- Question 9
You rub a plastic comb on your hair. When you hold it near tiny pieces of paper, they jump up and stick to the comb. Why does this happen?
- Question 10
Which of the following is the BEST example of static electricity in everyday life?
- Question 11
A metal spoon is an insulator because it is shiny and reflects light.
- Question 12
Why is it important to understand the difference between conductors and insulators?
- Question 13
If you rub a balloon with a cloth and it becomes negatively charged, what type of force acts between the balloon and your positively charged hair?
- Question 14
Dry air is better for building up static electricity than humid air.
- Question 15
When you rub two different materials together (like a balloon and wool cloth), what eventually becomes charged?
